PRINTING-TELEGRAPH.

To all whom it may concern:

Be it known that I, CHARLES K. JONES, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Printing-Telegraphs; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

My invention relates to printing-telegraphs; and it consists in a novelarrangement of circuit-forming relays, selectingrelays and associateddevices whereby by the operation of a single main-linecircuitcontrolling the selective action of the said relays any one of aplurality of type-bars or printing devices may be actuated at will andother actuations be accomplished for vari ous operating purposes.

Serial No. 517,742.

type-bars or similar printing-devices for the several characters; toprovide apparatus whereby the ordinary dot and dashcode of telegraphymay be received and translated into printed characters or be used forany other purposes desired; to provide a receiving printing instrumentadapted for operation by any type of transmitter ranging from theslowest to the highest speed instrum-ent.

I have illustrated three sets of printing and operating-magnets whichare controlled by what will be cesignated as circuitmaking relays and itwill be obvious from a further understanding of the method of operationthat these sets may be increased or diminished as may be desired byfollowing out the same method illustrated and I claim the privilege ofso doing,

I will now proceed to describe my invention with reference to theaccompanying drawings, in which one embodimentof the invention isillustrated and will then point out the novel features in claims.

In the said drawings, Figure 1 is a diagram showing an ordinaryhand-manipulated telegraph-key for a transmitter and the various relays,type-bar magnets, operating-magnets, and circuits of the correspondingreceiving instrument or printer. Fig. 2, illustrates one form oftype-bar mechanism adapted to be actuated by typebar magnets. Fig. 3, isa view in side elevation of one of the selecting-relays. Fig. '-ii-., isa horizontal sectional view on the line .1jh of Fig. 3.

In this system I employ for the transmission of the messages currentpulses, but said pulses vary in length, the short pulses representingdots and the long pulses representing dashes, and these pulses areusually, but not necessarily, alternately of opposite directions. Fortransmitting the characters of the English alphabet I may employ fromone to siX dots or dashes, or combinations of dots and dashes. Thisnumber of dots and dashes would give ample operating-magnets, whichwould be sixty-four magnets, permitting the transmission of thealphabet, numerals, punctuation-marks and for the operation of spacing,carriage-return and shift mechanism, such as are used on various well vknown electrical-type-writers and leaving a margin for any otherpurposes that may be desired. For transmitting a less number ofcharacters than are contained in the alphabet I may employ a fewernumber of dots and dashes and for transmitting a greater number ofcharacters than are provided for herein 1 may employ more than six dotsor dashes or combinations of dots and dashes.

In the accompanying drawings 1 have illustrated apparatus for receivingand printing adapted for operation by a code consisting oil a maximumnumber of tour dots or tour dashes or combinations of this number ofdots and dashes, this being done for the purpose of obviating anunnecessary lengthy description, as it is clearly obvious that thesystem may be ext-ended to any limit desired by following out the samemethod herein pursued.

Referring now to the drawings and at first to Fig. 1, the said figureshows an ordinary telegraph-hand-manipulated key for a transmitter, saidtype of transmitter being chosen for illustration on account of itssimplicity as compared with the Wheatstone transmitter or other types ofcomplicated transmitters, for be it understood that the receivingapparatus illustrated herein is adapted for operation by any type oftransmitter, all that is necessary being that the main-line relay beconnected to the receiving instrument as illustrated, viz. through theopposing-contacts and having the armature connected to one pole of abattery and the other pole of said battery connected to ground, so thatthe pulses received by the main-line relay will be relayed to thereceiver, and I claim the privilege of so operating, the transmitterbeing no part of my invention, but simply used in the illustration forthe purpose of explaining more fully the operation of the receiver orprinter; the operation of the transmitter will be described more fullyhereinafter; and a receiving instrument comprising a main-line relay 1,and a plurality of relays hereinafter described. The receivinginstrument and transmitter are connected by a line-wire 2. At thetransmitting end this line-wire passes through contacts of an ordinarypole-changer 3, forming a part of the transmitter and operated by alocal circuit controlled by contacts of the transmitter. At thereceiving end the line-wire 2, passes through main-line relay 1, whichin the instance shown is a polar relay, to ground. Main-line relay 1,controls two local circuits 4 and 5, connected to opposing contactpointsof the main-line relay. A battery 6, or other suitable source ofelectric energy is connected to ground and to the armature of main-linerelay 1. One or the other of circuits 4c and 5 is completed throughbattery 6 according as the said armature of relay 1, is in contact withthe right-hand or left-hand contacts of said relay, however this is nottrue until the first pulse actuates the armature of main-line relay 1into the abnormal position, this being for the purpose of opening acircuit between battery (5 and the instrument intervening between onecomplete operation of a characteristic signal and the beginning of thesucceeding characteristic signal. Circuit 5 is formed by the firstoperation of main-line relay 1, which operates relay 24 (designated asentrance-relay) into the abnormal position and relay 24: remains in suchposition until relay 22 is operated which operation completes a circuitpassing through the restoring-coils of relay 2 1 and thus restoring itto normal position; the operation of relay 22 also completes theprint-circuit which will be explained herein after. A condenser 8, isconnected across the contact-points of the relay 1, to reduce sparking.

Referring now to the transmitter, the same as shown in the drawings,consists of an ordinary hand-manipulated telegraph-key 9, adapted forengagement with contact 10, which is connected to magnet 3 of thepolechanger, thence to battery 11 by conductor, and by conductor frombattery 11 returning to key 9; key 9 is held normally in one position byspring 1 1-. Magnet 3 controls the spring-held armature of an ordinarypolechanger, which pole-changer in its operation places alternately onthe line-circuit sources of electric energy or batteries 12 and 13 ofopposite polarity, thereby producing in the line-conductor 2, currentpulses of opposite polarity.

The function of the entrance-relay 2 1-, is to protect the parts frominjury resulting from a prolonged energization from battery 6,intervening between characteristic signals.

On account of a thorough description be ing made explaining theoperation of the instrument in a number of characteristic signals whichfollow, a brief description of the instrument will here sul'lice: Thereceiving instrument consists of a number of polar relays havingrestoring-coils and a number of neutral relays said polar and neutralrelays being designated as circuittorming relays; a group of polarrelays having restoring-coils being desi nated as circuit-making relaysand number of neutral relays being designated as selecting-relays. Thereceiving instrument as illustrated is in the normal or open-circuitposition with no electric current into its parts in perceptible activityexcept to the mainline relay 1 from battery 12. There are fourselecting-relays corresponding to the maximum number of pulses composingthe code herein used and these relays are not operated except by thelong or dash pulses. For purposes of description the selectingrelayswill be designated as in clusters on account of said relays of thesecond, third and fourth clusters having a plurality of contact-pointswith spring-plates for engagement therewith as illustrated in Figs. 3and at. The relay of the first cluster is an ordinary neutral relayhaving two contactpoints, the relay of the second cluster has fourcontact-points and four spring-plates for engagement therewith, therelay of the third cluster has eight contact-points and eightspring-plates for engagement therewith. and the relay of the fourthcluster has sixteen contact-points and sixteen springplates forengagement therewith. The contact-points of the selecting-relays areconnected one to another as follows: One of the contact-points of therelay of the first cluster is connected by conductors to eachcontact-point of two of the contact-points of the relay of the secondcluster, the other contact-point of the relay of the first cluster isconnected by conductors similarly with the remaining two contact-pointsof the relay of the second cluster, the four spring plates of the relayof the second cluster are connected by conductors in a similar manner tothe contact-points of the relay of the third cluster, and in like mannerthe re maining clusters are connected one to another, the relay of thefourth cluster having therefore sixteen contact-points connected byconductors to the preceding cluster, and sixteen spring-plates remainingare connected by conductors to their respective printing oroperating-magnets of a set which is designated as set 25 the otherterminals of said magnets are connected to amultiple lead 103, thence bywire 10-1, through the armature of circuit-making relay 29, wire 106,through armature of circuitmaking relay 28 and to ground at 108. Threeof the spring-plates of the relay of the last cluster are connected incircuits passing through the coils of their respective circuit-makingrelays 28, 29, 30 and 31, and to ground, the object of which being tocontrol the sets 25, 26 and 27. The printing and operating-magnets inset 26 are connected by conductors to their respective spring-plates ofthe-relay of the last cluster and the other terminals of said magnetsare connected to a multiple lead 123, to contactpoint of circuit-makingrelay 30, the armature of relay 30 connected by conductor 124 to acontact of relay 28,the armature of circuit-making relay 28 is connectedto wire 107 leading to ground at 108. The printing and operating magnetsof set 27 are connected in a similar manner to their respectivespring-plates of the relay of the last cluster and the other terminalsof said magnets are connected to a multiple lead 132 and thence to acontact-point of circuit-making relay 31, the armature of relay 31 isconnected to ground at 133. Two printing or operating-magnets only areshown in each of the sets 26 and 27, but it will be understood thatthere are circuits available for operating thirteen of such magnets ineach of said sets and the claims will there= fore be drawn accordingly.

It will be noted that the circuits available for operation by theselecting-relays are in geometrical progression. The printing andoperating-magnets in set 25 are illustrated as being normally in circuitwith contacts of said selecting-relays of the last cluster and if it bedesired to cut out of circuit set 25 and to cut into circuit set 26, itwill be necessary to operate the characteristic signal controlling theoperation of circuit-making relay 28, which will consummate the purposeby opening one multiple lead and making another multiple lead good toground through circuits controlled by the circuitmaking relays; if it bedesired to cut outof circuit the set 26 and to cut into circuit the set27, it will be necessary to operate the characteristic signalcontrolling the operation of circuit-making relays 29, 30 and 31, whichrelays are connected in electrical series for simultaneous operation andthe desire is consummated by opening one multiple lead while anothermultiple lead is made good to ground; to restore the sets totheir normalposition it is necessary to operate the characteristic signalcontrolling the operation of the circuit-making relays 28, 29, 30 and31, which relays are connected in electrical series for-simultaneousoperation and the purpose is accomplished by opening two multiple leadswhile the multiple lead of set 25 is made good to ground.

The magnets comprising the sets 25, 26 and 27, may be termed type-barand operating-magnets or printing and operating-magnets, though ashereinafter shown, certain of these magnets may operate shift mechanism,space mechanism, carriage-returning mechanism, or the like.

Each selecting-relay is connected in a circuit controlled by acorresponding circuitforming relay and each such circuit is adapted foroperation successively, by the dash or long pulses. For convenience ofdescription we will designate the four circuit-forming relays whichcontrol the four selecting-ree lays as the dash-relay, or dash-relays.

There are two sets of neutral relays comprising the circui t-formingrelays, which sets comprise relays adapted for operation successively,the last relay in each set being operated only by the dashes or longpulses. A switch 57, in one set, and switch 77, in the other set areadapted for engagement with the contacts 143 and 144.- and 143 and 14. 1respectively, for the purpose of cutting out of circuit one or more ofthe relays in said sets, thereby adapting the receiving instrument to afaster speed. Should a slower speed than is herein illustrated bedesired then it will be necessary to increase the numher of the relayscomprising said sets, and I claim the privilege of so doing. The twosets of neutral relays are controlled by the main-line relay, one setbeing controlled by one contact and the other set being controlled bythe other contact; one set enibracing relay 17, is for completing thecircuits controlling the operation of the dash relays 109, 110, 111 and63 and the lastnamed relays control the selecting-relays as previouslystated; the other set of neutral circuit-forming relays is for thepurpose of completing the print-circuit and the restoration-circuit,relays 22 and 23, designated as the print-relay and the restoring-relay,when operated accomplishing this purpose. It will therefore be obviousthat a print and restoration may be el'lected with the second, fourth,sixth or eighth pulse operated the requirement being that thetransmitter remain in the normal position long enough for the relays 18to 23 inclusive to be operated successively.

Two printing or operating-magnets may be controlled by two pulsesoperated by the main-line relay said magnets being in set- 25; twomagnets in set 26 and two of said magnets in set 27 may be controlled bytwo pulses operated by the main-line relay, but as previously explainedthe multiple leads controlling the circuits of the sets must be changedby the operation of the circuit-making relays before the magnets in sets26 and 27 can be operated; similarly, two others of said magnets may becontrolled by the oper ation of tour pulses by the main-line relay; atotal of sixteen selecting-circuits are available for operation in set25 by the operation of the code 01 two to eight pulses by the main-linerelay. The dash-completing relay 17, is operated by a long pulse or dashoperated by the main-line relay in the first, third, fitth and seventhpulses. The restoration leaves the various relays in position for thefirst pulse operated by the main-line relay 1, beginning acharacteristic signal; it the first pulse be a dot or short pulse thepolar relays of the circuit-forming relays are not operated, but it thefirst pulse be a dash then relay 17 is operated thus completing acircuit which passes through the armature of relay 39 via conductor to aplate contact on the armature of relay 40, but said plate is insulatedfrom said armature, thence to contact of relay 10, thence through thecoils of the first dash-relay 109, and to ground and thus operating saiddash-relay; the operation of the dash-relay 109 completes a circuitthrough. the contacts of relay 109 thus operating the selecting-relay ofthe first cluster and the relay 109 and the said selecting-relay willremain in such position until the restoration takes place; the secondpulse if a short pulse will not operate the extreme relays 22 and 23 butwill operate polar relays -39 and 4:0 in a circuit passing through thecoils of said relays and to ground and thereby severing a circuit by theoperation of relay 10 through which relay 109 was operated, and alsoforming a circuit through the armature of relay 40 and its lower contactfor the operation of relay 43 by the third pulse, and the operation ofrelay 39 forming a circuit through its other contact whereby the thirdpulse may operate the second dash-relay 110, it perchance there be adash occurring in the third pulse; the third pulse operated will operatepolar relay 4:3, in a circuit via conductor 41, through the armature ofpolar relay 10 and its lower contact, through the coils of relay 43 andto ground, and thus forming a circuit through the contacts of relay 13for the operation of the fourth pulse; if the third pulse be a dash thenrelay 17 is operated thereby completing a circuit from wire 60, throughthe armature of polar relay 39 and its lower contact, thence byconductor through the contact and through the plate on the armature ofrelay 46, but said plate is insulated from said armature, thence byconductor through the coils of the second dash-relay 110, and to ground,and thus operating the second dash-relay, which second dash-relay willin turn complete a circuit through its contact which will operate theselecting-relay of the second cluster; the fourth pulse will operaterelays 4L6 and 47, by a circuit passing through the armature of relay 43and its lower contact and through the coils of relays 16 and 47, toground, thus severing the circuit through which the second dash-relay110 was operated, the circuit being opened by the armature of relay 46leaving the upper contact, the change of position of the arinature ofrelay 416 also torming a circuit for the operation of relay 50 by thefifth pulse, the operation of relay 47 forming a circuit through itscontacts for the operation of relay 111, the third dash relay, by thefifth pulse; the operation of the fifth pulse will operate polar relay50 in a circuit via wires 41 and tS through the armature of relay 46 andthrough the coils of relay 50 to ground, thus forming a circuit throughthe contacts of relay 50 for the operation of the sixth pulse; it thefifth pulse be a dash then relay 17 is operated thus completing acircuit via conductor 60, through the contacts and armature of relay 17,through the upper contact and the plate on the armature of relay 54,said plate insulated from said armature, through the coils of relay 111,the third dash-relay, and to ground, thus operating the third dashrelay, which in turn will operate the selecting-relay in the thirdcluster; the sixth pulse operates polar relays 5 1 and 55 in a circuitvia wire 38, through the armature and up per contact of relay 51,through the armature and lower contact of relay 50, and through thecoils of relays 54 and 55 and to ground, thus severing the circuitthrough which the third dash was effected said opening occurring whenthe armature of relay 54 leaves its upper contact, and when saidarmature makes its lower contact, a circuit is formed for the operationof relay 51 by the seventh pulse, the operation of relay 55 forms acircuit for the operation of the fourth dash-relay if there be oneoccurring in the seventh pulse; the seventh pulse operates relay 51 in acircuit passing through the armature of relay 54 and through the coilsof relay 51 and to ground, thus severing through the contacts of relay51, the circuit which operated the relays 54 and 55 in the sixth pulseand efiecting a saving in operating current; if the seventh pulse be adash then relay 17 is operated and a completing circuit is operated fromground 7, through battery 6 through armature of relay 1, wire 4, throughthe armatures of relays 15, 16 and 17 to wire 60, it will be understoodfrom what has previously been stated that the relays 15, 16 and 17 areoperated successively thus forming a circuit through their contacts towire 60, from wire 60 to Wire 61, through the armature of relay 55, wire62 and through the coils of the fourth dash-relay 63 to ground, thusoperating relay 63, which in turn completes a circuit through itscontacts which operates the fourth cluster relay in a circuit fromground 64, through multiple lead 66, through the armature and contact ofrelay 63, wire 67, through the coils of relay 68 and to ground at 69; ifall the four pulses operated be dashes then all the polar relayscomprising the circuit-forming relays will now be in the abnormalposition; the eighth and final pulse comprising the code of operationwill energize the magnets of polar relays 39, 40, 46 and 47, but therewill be no actuation of the armatures of said relays for the reason thatthese armatures are already in the abnormal position, and saidenergization will continue until the entrancerelay is operated whichwill break the connection to battery 6 and deenergization will follow;the eighth pulse will operate the neutral relay set comprising relays 18to 23, inclusive, and the operation of the final. relays 22 and 23,which operation occurs successively, will cause a print to ensue orcause the energization of an operating-magnet from a circuit startingfrom round at 89, through the coils of entrance relays 24, therebyrestoring entrance-relay 24 to normal position, wire 90, through battery91, through the contacts of relay 22, wire 92, through the armature ofthe selecting-relay of the first cluster and through the contacts ofsaid relay and through the contacts of others of the selecting-relays tothe selected printing or operating-magnet, through multiple lead 103,wire 104, through armature of circuit-making relay 29 L0 Wire 10%,through armature of circuit-making relay 28 and to ground, thusenergizing said selected printing or operating-magnet; the operation ofrelay 23 which follows very quickly the operation of relay 22, completesa circuit through the restoring-coils of all the polar relays except theentrance relay and the parts are restored to normal position.

The operation of this apparatus is as follows: supposing, for example,that the message to be transmitted consists of three dots followed by adash; the transmitter 9 is depressed or closed so that it makes contactwith 10, and then said transmitter is released so that it will becarried back to the normal position by spring 14; this will energizemagnet 3, and the pole-changer actuated so that battery 13 is placed tothe line and circuit 4 will be completed to relay 15. The firstoperation being a dot or short pulse, the armature of the main-linerelay 1, does not remain in contact with circuit 4 long enough for theoperation of relays 16 and 17 to take place; another circuit 32 isconnected to circuit 4 passing through an adjustable resistance 33thence through the coils of polar relay 24, the entrance-relay, toground, thus effecting a circuit whereby the main-line relay 1, maycause operations of the various parts when its armature is returned tothe normal position after the first pulse; when the armature or"main-line relay 1 is actuated to the normal position a circuit is madeas follows: wire 5, armature of polar relay 24, wire 34, relay 18 toground; as the relay 1 will not remain in the normal position long theremainder of the relays 19, 20, 21, etc. embracing the neutral relay setwill not be operated; a branch circuit 35 is connected with wire 34which leads to the armature or relay 18; another branch circuit isconnected to wire 35, it being conductor 36, thence to wire 38, throughthe coils of polar relays 39 and 40 to ground, thus actuating thearmatures of relays 39 and 40 to the abnormal position and they willremain so until all the parts are restored to normal position. The nextoperation being a dot, the transmitter is operated the same as with thefirst dot and the main-line relay 1 is operated into the abnormalposition and the result will be the same as described in the first dotbut there will be no further actuation of the entrance-relay 24 untilthe parts are restored to normal; an additional circuit will now beoperated as follows: connected with wire 4 is a branch wire 41, leadingto the armature of polar relay 40, thence to wire 42 and through thecoils of polar relay .43 to ground, thus actuating the armature of polarrelay 43 into the abnormal position.

The second dot being completed the armature of main-line relay 1 isactuated into the normal position and the following circuits are made:relay 18, is operated as in the previous operation and in additionthereto a circuit is made from wire 81 to wire 35, wire 36, wire 38,wire 1%, armature of polar relay 18 to wire 15, through the coils ofpolar relays d6 and 17 to ground, thus op erating relays 16 and 47 intothe abnormal position.

The third dot calls for the same operation of the transmitter as theprevious dots and the operations on the parts will be the same as theprevious ones, except that the circuit will now run from wire a to wire4:1, wire 18, through armature of relay 16, wire 49, through the coilsof relay 50 and to ground, thus operating relay 50. The third dot beingcompleted the armature of the main-line relay 1, is operated into thenormal position with the following result: in addition to the operationof relay 18, the circuit goes from wire 341 to wire 85, to wire 36, wire88, armature of relay 51, wire 52, armature of relay 50, wire 58,through the coils of relays 54s and 55 to ground, thus operating relays51 and The next transmission being a dash, the transmitter is held incontact with 10, for a longer period than for the dot and the followingoperations result: relay 15 is operated thus causing another circuit tobe made from wire a, through the armature of relay 15 to wire 56, switch57, wire 58, magnet of relay 16 and to ground, the energization of themagnets of relays 15 and 16 resulting in the actuations of theirrespective armatures, from wire 58 through the armature of relay 16 towire 59, thence to magnet of relay 1'? and to ground, thus energizingthe magnet of relay 17 and causing its armature to actuate, thisactuation causing another circuit to be made from wire 59 through thearmature of relay 17 to wire 60, thence to wire 61, armature of relay 55to wire 62, through the coils of relay 63 to ground, thus causing theoperation of relay 63; another circuit is now made fro-m ground 6-1through battery 65, wire 66, through armature of relay 63, wire 67,magnet of relay 68 and to ground at 69, thus actuating the armature ofrelay 68, there to remain until the parts are restored to normal; theoperation of relay 68 reverses the positions of spring-contacts 70 and71, connection being now broken between 70 and 72 and connection beingmade between 71 and 73. Another circuit makes follows:

wire 4 to wire 41-1, wire 74: through the armature of relay 541, to wire(5, through the coils of relay 51 and to ground, thus actuating thearmature of relay 51.

The dash being now completed the armature of main line relay 1, isactuated into the normal position and the following circuits ensue: wire5, through armature of relay 24, wire 34:, through magnet 18 to ground,thus operating relay 18, which makes a circuit from wire 3st, throughthe armature of relay 18, to wire 76, switch 77, wire 7 8, throughmagnet of relay 19, and to ground; the armature of relay 19 is actuatedand make another circuit from wire 78, branch wire 79, through thearmature of relay 19 to wire and through the magnet of relay 20 and toground, this ope "ates relay 20 and makes circuit from wire 80, branch81, through the armature of relay 20 to wire 82, through the magnets ofrelays 21 and 22 and to ground, thus operating the relays 21 and Theoperation of relay 22, makes the following circuit: from ground at 89,through the coils of relay 2 1 (the entiancerelay), to wire 90, throughbattery 91, through. the armature of relay 22, wire 92, through thearmature of relay 93, conductor 941 to springcontact 95, wire 96 tospring-contact 97, wire 98, wire 99, spring-contact 100, wire 101,through type-bar magnet 102 to wire 108, wire 10st, through armature ofrelay 29 to wire 106, through armature of circuit-n'iaking relay 28 towire 10'? and to ground at 108, thus restoring the entrance-relay 24: tonormal position and effecting an energization of the type-bar magnet102, and the corresponding type-bar is operated.

Immediately following the print, the parts are restored to normal in thefollowing manner: when relay 21 is operated another circuit is made fromwire 82 to wire 88, through the armature of relay 21 to wire throughmagnet of relay 23 and to ground, thus operating relay and the operationof relay 23 completes a restoring-circuit from ground 85, throughbattery 86, through armature of relay 28 to wire 87, thence through therestoring-coils of polar relays 39, 10. 16, it, 54:, 13, 50, 51, 109,110, 111, and (as: and to ground at 88. The operation of polar relays109, 110, 111 and 63 to the normal position breaks the circuitscontrolling relays 93, 112, 1.13 and 68 and their respective springsactuate their armatures to the normal position. It will he understoodhowever, that in the operation just described only one of these relayswere operated, it being relay 68.

It will be seen that by following out the method previously described, acircuit may be completed through any one of the various type-bar magnets25 at will, and through any one of the corresponding magnets in sets 26and 27 after the proper operations are made with the circuit-makingrelays as explained.

I will now describe the operation of the circuits controlling the setsof printing and operating-magnets: if the set- 26 is desired to be cutinto circuit with the selecting-relays, four dashes will be requir d toeffect the purpose and the relays 93, 112, 113 and 68 will be operatedand a circuit will be made as follows with the completion of the saidfour dashes, similarly as described in the energization of type-barmagnet 102: from ground 89, through the coils of entrance-relay 24:,wire 90, battery 91, through armature of relay 22, to wire 92, throughthe armature of relay 93, wire 94, wire lltt, spring-contact 115, wire116, spring-contact 117, wire 118, spring-contact 119, through themagnet of circuit-making relay 28 and to ground, thus operating relay28. If the same operations are now effected which resulted in theenergization of the typebar magnet 102, in the set 25, as previouslydescribed, the circuit will be as follows: from springcontact 100, wire101, wire 126, typebar magnet 125, wire 123, armature of relay 30(circuit-making relay), wire 12%, armature of circuit-making relay 28,wire 107 and to ground at 108, thus energizing the typebar magnet 125,in set 26, which magnet corresponds with the type-bar magnet 102 in setTo cut into circuit the third set 27, with the selecting-relays, threedashes are necessary to effect the pro-per operations of circuit-makingrelays 29, 30 and 31 and when said operations are accomplished thefollow ing circuit will be made: from ground at 89, through the coils ofentrance-relay 24, wire 90, through battery 91, armature of relay 22,wire 92, armature of selecting-relay 93, wire 94, wire 1'14,spring-contact 115, wire 116, spring-contact 117, wire 118, wire 128,spring-contact 127, through the coils of the circuitmaking relays 29, 30and 31, to ground at 165, resulting in the operation of the threelast-named relays, which will make a circuit as follows, when it isdesired to energize the type-bar magnet 131, in set 27, said type-barmagnet corresponding to the type-bar magnets 102 and 125 in sets 25 and26, and assuming that the circuit has been operated similarly aspreviously described in the energization of type-bar magnet 102, so thatspring-contact 100, is operated into engagement with wire 99: fromspring-contact 100, wire 101, wire 126, wire 130, type-bar magnet 131,wire 132, armature of circuitmaking relay 31 and to ground at 133, thusenergizing type-bar magnet 131. To restore the sets 25, 26 and 27 tonormal, it will be necessary that the proper combination of operationsbe effected, similarly as previously described, which will result in thespring-contact 13 1 being brought into en gagement with wire 135, whichwill result in the operation of the circuit-making relays 28, 29, 30 and31, which relays are connected in electrical series for simultaneousoperation, via wires 160,161,162,163, and 164 and to ground at 165. Thearmatures of all the polar relays tend to remain in contact withwhatever contact-pomt they are 111 contact at the time. These relays areprovided with a second or restoring-circuit for returning theirarmatures to the normal position.

In Fig. I have shown mechanism for operating type-bars byelectromagnets, the parts-there shown being an ordinary typewriter rollor platen 138, type-bars 139, connected by links 140, to armature-levers1411, adapted to be operated by the printingmagnets 142; but it will beunderstood that I do not limit myself to any particular printingmechanism and that the mechanism of any of the well-known electricaltypewriters maybe used. Further, it will be understood that certain ofthe magnets 1&2, may operate shift, spacing, and carriagereturnmechanism such as are commonly used in electrical type-writers, suchmagnets acting directly or as relays to complete the circuit of othermagnets.

In Figs. 3 and 41. I have shown a relay for operating a plurality ofoppositely-opposed spring-contact connections, adapted'to be operated bypolar relays 110, 111 and 63, but it will be understood that I do notlimit myself to this particular type of springcontact connection as suchparts may be made in various ways. Referring to the parts, 68 is anarmature-lever pivoted on support 146. said support having a base 147;adjustable screws 150 and 150 are carried by supports 146 and 148, tolimit the travel of the armature 68. Screws 150 and 150 are adapted tocarry wires 99 and 99. Another support 149, carries two sets ofoppositely-opposed spring-plates, adapted for alternate engagement withscrews 150 and 150. Screws 151 and 151 are for holding wires 101 and101. A spring 157 holds the armature 68 normally in one position andmagnet 68 is adapted when energized to actuate the said armature intothe abnor mal position. Armature 68 is provided with insulation on itsfree end and oscillates between the screws 150 and 150 and being placedbetween the spring-plates 100 and 100, said plates are brought intoengagement with the screws 150 and 150 alternately, thus making aplurality of connections by the actuation of one armature.

It will be obvious that my invention is susceptible of many variationsand modifications without departing from the principles herein setforth, and I do not limit myself to the details of construction and arrangements of the parts herein illustrated and described.

The principal reason for transmitting messages by current pulses ofalternatelyopposite direction is that polar instruments work better on along line than do neutral instruments. Then preferred, the mainlinerelay of the receiver may be a neutral relay, and in such case thetransmitter need not be so constructed as to reverse current polarity.Fig. l

It will be understood that the main-line relay of the receiver may beconnected in series with the receiving relay of a duplex or quadruplex,thus enabling my receiver to operate in connection with such systems.
